บทคัดย่อ (EN): The involvement of defense related enzymes and secondary metabolites in resistance of Hevea brasiliensis clones against the leaf disease pathogen Corynespora cassicolawas studied. Changes in PAL, TAL, CAD, total protein and total free amino acid were evaluated after C. cassiicola infection on the H. brasiliensis clones RRII 105, PB 260, RRIM 600 and GT 1. The former two clones show susceptible and the later two resistant reaction against the isolate of C. cassicola used. The time course accumulation of defence enzymes triggered by pathogen inoculation showed greater activity in clones RRIM 600 and GT 1. A steep rise in activity of PAL was noticed in GT 1 at the initial stages of disease development and it continued even at the later stages of infection. A significant increase in activity of TAL was also noticed in both RRIM 600 and GT 1. The CAD activity was accelerated upto 72 h after infection in all these clones but a reduction was observed in RRII 105 and PB 260 at 96 h. While protein accumulation was noticed up to 96 h of infection in RRII 105 and PB 260, it declined after 72 h in GT 1 and RRIM 600. The total free amino acid content was greater in uninoculated plants of RRII 105 and PB 260. It reduced on infection with C. cassicolain all the clones.
